mental arithmetic
Calculating without paper
Mental arithmetic is calculation done in the head, without writing, calculators, or other aids.
The phrase often appears in educational contexts: We practiced mental arithmetic every morning.
Someone good at mental arithmetic can quickly compute tips, split bills, or estimate totals while shopping.
